My fiance was diagnosed with OCD, when she was 15(had her 45th birthday two weeks ago) and has started obsessing again(at least it feels like she is), about my having an STD. This is despite the fact that, every possible STD test I took(due to a prior fiance's sexual history), has been negative. But my fiance is not satisfied with what I told her. I even spent $100+ on STD tests that were not covered by my insurance.
